The present invention has relation to sheet metal pipe corrugating andseaming machines, and it consists in the different parts and combinationof parts hereinafter described, and particularly pointed out in theclaims.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

In the accompanying drawings 1, represents the legs or standards uponwhich the machine 5 proper rests, and is supported at the requiredheight. To the top or upper end of the legs or standards 1, are securelyattached in any convenient and well known manner, the bars 2, which barsare formed of a length to correwe spend with the length of the machinedesigned to be constructed. The bars 2, are

held in proper parallel position by means of suitable cross-bars andtie-rods or bolts, which parallel cross-bars and tie-rods constitute theframe of the machine proper.

To the parallel bars- 2, are attached by means of suitable clampingbolts or their equivalents, the. brackets 3, which brackets are locatedat intervals along the bars 2, and are provided with the rollers 4, saidbrackets and rollers being located and arranged substantially asillustrated in Figs. 1, 8, 20, and 21.

Upon the rollers 4, are located the carriage sills 5, which carriagesills are provided with the rack-bars 6, which rack-bars are formed of alength to correspond with the length of travel calculated and designedto be given to the backward and forward reciprocating carriage.

For the purpose of imparting a reciprocating movement to the carriageproper, the pinions 7 are provided, which pinions are securely attachedin any convenient and well 4 known manner to the shaft 8, said shaft andpinions so located and adjusted, that the pinions 7, will mesh with therack-bars 6. For the purpose of communicating rotary motion to the shaft8, said shaft is provided with the beveled gear wheel 9, which beveledgear wheel meshes with the pinion 10, which pinion 10 is securelyattached to the shaft 11, which shaft is connected with the belt pulleys12, which belt pulleys are provided with any common reverse clutchmechanism, which mechanism may be of any. desired style or kind,inasmuch as the reverse mechanism forms no particular part of thepresent invention, except that a reverse motion must be given to theshaft 11, to carry out the operations of the machine proper, whichoperations are to be hereinafter described.

To the rear end of the machine is located the pivoted arm 13, whichpivoted arm is attached to the bar 14, or its equivalent, which bar 14is attached to the rear end of the carriage sills or bars 5. For thepurpose of assisting in holding the parallel bars 5, in proper position,the bracket 14, is provided, said bracket being also for the purposehereinafter described. For the purpose of securely holding the variousmandrels,such as 15, and the other mandrels hereinafter proper position,and at the same time preventing the mandrels from moving end wise, theclamps 16 and 17 are provided, which clamps may be of the form shown inFigs. 1, 2, 4, 22, and 23.

For the purpose of supporting the difierent mandrels, the bar 14, islocated directly below the clamp 17, and the set-screw 18, and uponwhich bar orbracket, the clamp 17 moves or slides at the time themandrel secured by said clamp is moved out of alignment with thecarriage proper, as illustrated in Fig. 23, said movement being given tothe mandrel for the purpose hereinafter described.

At or about the transverse center of the ma chine proper is removablyattached the die described in.

frame or head 19, which die frame or head is held in proper position, bymeans of the brackets 20, which brackets are securely attached in anyconvenient and well known manner to the sills 2 or their equivalents.

For the purpose of removing any particular die head, such as 19, and thediflerent dies attached to the head the brackets 20 are provided withthe grooves 22, which grooves are located substantially as illustratedin Fig. 22.

It will be understood that different dies are to be employed for theformation of difierent sized and shaped pipes; and it will also beunderstood that various styles of mandrels, such as 15 and 15 are to beused for seaming and corrugating pipes, and that the mandrels and diesare to correspond with each other, with reference to the corrugating ofthe pipe; that is to say a particular set of (lies, and mandrel are tobe used to produce a {dam ticular sized or shaped pipe.

In the drawings I have illustrated various kinds of mandrels, which areto be used both for seaming and corrugating; but it will be understoodthat various changes, both as to size and form can be made in themandrels and dies, without departing from the nature of my invention,inasmuch as a reciprocating carriage, and means for reversing thecarriage to produce a reciprocating movement must be provided for in allinstances.

In Figs. 6, 15, and 17, I have illustrated in cross section mandrelsdesigned and calculated for compressing and finishing the lon gitudinalseam of a pipe; these mandrels are each provided with the ledge orflange 21, which ledge or flange extends the entire length of themandrel, or that much of the mandrel over which the pipe is to beplaced.

In Fig. 15, a portion of the seaming wheel 22 is illustrated, whichseaming wheel is provided with the flange 23, which flange is soarranged that it will come opposite the ledge or flange, as illustratedin Fig. 15.

For the purpose of holding the pipe, calculated to be seamed orcorrugated in proper position upon the mandrel over which the pipe isplaced, the yielding pins 24, are provided, and are so located andarranged that their curved faces will extend a short distance above, orbeyond the periphery of the mandrel, substantially as illustrated inFigs. 1, 5, 6, and 17. For the purpose of prevent ing the yielding pins24, from interfering with the seaming wheels or corrugating dies, saidpins are held in their normal position by means of the springs 25, whichsprings are located within the chambers 26,--and around the portions orextensions 2.7 of the pins 24.

It will be understood that as the various mandrels are movedlongitudinally through the die heads or under the different seamingwheels that the pins 24 will be pressed inward toward the center of themandrel, thereby preventing said pins from interfering in any mannerwith the operation of the various dies k or seaming wheels.

For the purpose of preventing the ends of the pipe from striking thepins as said pipe is slipped on and off the mandrel, the outer faces orheads of the pins 24 are curved, so as to bring ends of said pins belowor on a level with the periphery of the mandrel. For the purpose ofsupporting the mandrel and its pipe directly below the seaming wheel,and dies, the roller 29 is provided, and located substantially asillustrated in Fig. 10.

To the die head 19 are attached in any convenient and well known mannerthe blocks 30, which blocks are provided with the compressing orcorrugating wheels 31, which compressing or corrugating wheels areproperly journaled to the blocks 30, which blocks are located andarranged substantially as illustrated in Fig. 11.

It will be understood that the periphery of the diiferent corrugatingand compressing wheels 31, should be located at an equal distance from acommon center, which common center is also the center of the mandrel. InFig. 12, the finishing wheels or dies are illustrated, said finishingwheels and dies 30 being located and arranged substantially asillustrated in Fig. 12, and are for the purpose of completing thecorrugating of the pipe; the front corrugating wheels or dies act onlyto crush or start the bending of the metal. It will be understood thatthe number of compressing wheels in each set are to correspond with thenumber of corrugations to be given the pipe.

For the purpose of providing an adjustment for the difierent thicknessesof sheet metal from which the pipe is made the set-screws 31 areprovided. It will be understood that the material for the pipes is edgedfor their seams and formed round in the usual manner, which process oroperation has no particular reference to the present invention, exceptto properly formulate the material from which the pipes are seamed andcorrugated.

For the purpose of providing a means for placing the pipe of skelp uponthe mandrels, the various mandrels are attached to the pivoted arm 13,so that the mandrels can be swung or turned to the position illustratedin Fig. 23, after the pipe has been properly placed upon the mandrel,the mandrel and pipe or skelp are placed in the position illustrated inFigs. 1 and 22, which position brings the pipe or skelp, and its mandreldirectly opposite and in line with the corrugating dies or wheels, orseaming wheel, as the case may be, which position places the pipe andits mandrel in proper position to be moved forward through thecorrugating die head or under the seaming wheel.

For the purpose of properly locating and guiding the mandrel and itspipe through the corrugating die head, or under the seaming wheel, theroller 29*, is provided, which roller is grooved, as illustrated in Fig.8, it being understood that the grooved roller 29", is especially forthe purpose of providing a guide to properly start or enter the mandrelandits pipe into the corrugating die head or under the seaming wheel.

For the purpose of starting or entering the forward end of the mandrel,and its pipe into the corrugating die or under the seaming wheel thespring 32 is provided; one end of said spring is attached to thecross-bar 33 or its equivalent, and the opposite end of said spring isattached to the rock-bar 34, which rock-bar is located substantially asillustrated in Fig. 20, and as shown in said Fig. 20, the bottom orlower end of the'rock-bar is pivotally attached to the cross-bar 34*, orif desired said rock-bar may be rigidly attached to the cross-bar 34,and the cross-bar journaled as the object of said spring can beaccomplished equally as well with either construction.

To the traveling carriage is attached the downwardly extending arm 35,which arm is located substantially as illustrated in Fig. 20, and is forthe purpose hereinafter described.

To the arm 36 or its equivalent is pivotally attached the operatinglever 37, which lever is located substantially as illustrated in Fig.22. To one end of the operating lever 37 is pivotally attached the rod38, which rod extends forward to a point about midway between the beltpulleys 12, and has pivotally attached thereto the shift-bar 39, whichshiftbar is for the purpose of reversing the motion of the shaft 11, itbeing understood that the belt pulleys 12, are rotated in oppositedirections by means of one of 'the belts upon said pulleys, being openand the other crossed.

The downwardly projecting arm 35, is so adjusted upon the carriage, thatwhen said carriage nears its stop as it moves backward, the arm 35 willcome in contact with the rockbar 34, and move the upper end of therockbar a short distance, thereby converting the spring 32, into a livespring After a pipe or skelp has been properly placed upon a mandrel,and the mandrel and pipe swung into proper position to movelongitudinally, the free end of the operating lever 37, is moveddirectly upward and out of the notches, which notches will hereinafterbe described.

To one of the sills 2, is securely attached the bracket 40, whichbracket is provided with the notch 41, said notch being for the purposeof holding the operating lever 37. When the carriage is moved backwardas far as itis designed to travel, the arm 42 which is attached to oneof the carriage sills, and moves back and forth with the carriage willbe brought into the position illustrated in Fig. 20, which positionbrings the notch 43, in line with the notch 41, thereby locking theearriage by reason of the operating lever dropping into the notchesinasmuch as the lever disengages both belt pulleys, by means of the ICCshift bar 39, and clutch mechanism. When the operating lever 37 iselevated so as to disengage it from the notches 41 and 43, the carriagetogether with its mandrel will be moved forward toward the front orpower end of the machine, by reason of the spring 32 pulling on therock-bar 34, which moves the carriage forward sufiiciently to enter themandrel and its pipe or skelp into the die head, or under the seamingwheel, as the case may be.

After the mandrel and its pipe or skelp has been properly started orentered, the operating lever 37 is moved toward the rear end of themachine, which'in turn applies power and the carriage moves forwarduntil the pin 44, comes in contact with the free end of the operatinglever 37, and moves the free end of said lever toward the front or powerend of the machine, which action reverses the rotation of the shaft 11,by means of the shift-bar 39, thereby reversing the movement of thecarriage and its mandrel.

For the purpose of carrying the lever 37 over the notch 41, the plate 45is inclined upon its top or upper edge as illustrated in Fig. 20,thereby elevating the operating lever, as the plate 45 passes under saidlever. It will be understood, that by means of the pin 44 and the plate45, that one complete forward and backward movement of the carriage willbe made, and said carriage come to a stop upon its backward or returnmovement by reason of the shoulder 46, moving the operating lever towardthe notch 41, until the notch 43 comes in line with the notch 41, atwhich time, the operating lever 37, drops into the notches.

For the purpose of preventing the carriage sills or bars 5, fromvibrating or springing as they are moved longitudinally, and at the sametime forminga guide for the movements of the carriage, the bottom orunder side of the sills 5, are provided, with the plates 47, whichplates are formed somewhat wider than the carriage sills, and are soformed for the purpose of causing the top'or upper ends of the brackets3 to engage said plates, as illustrated in Fig; 21. If desired therackbars 6, may be formed separate from the plates 47, and attached tosaid plates in any convenient and well known manner, or the rack-barsmay be formed integral with the plates 47 if desired.

For the purpose of supporting the pipe, after the mandrel has beenremoved as hereinafter described, and at the same time assisting insupporting the mandrel, the rollers 48 are provided, which rollers arelocated and arranged substantially as illustrated in Figs. 1, and 22,and are held in the desired position by means of the brackets or arms49, which brackets or arms are attached in any convenient and well knownmanner to the bars 2.

For the purpose of stripping the pipe from the mandrel as the carriagemoves backward, the stripper 50 is provided, which stripper is soadjusted that its front edge or face will come against the rear end ofthe pipe, and thereby prevent the pipe from moving with the mandrel. Thestripper 50, is attached to the brackets or arms 51.

In Fig. 13, the stripper 52 is somewhat modified from that shown in Fig.9, but it is for the same purpose, and is pivotally attached at its topor upper end to the arms 53. The strippers are so adjusted thatasthemandrel and its pipe moves under the strippers or stripper, thethickness of the pipe will cause the stripper to be moved as indicatedin the dotted lines, Fig. 10, when the rear end of the pipe has passedthe stripper, it will assume the position illustrated in Fig. 10, whichposition brings it into operative place.

For the purpose of providing a means for removing the pipe from themachine proper, after the mandrel has been withdrawn from said pipe, thearms 54 are provided, which arms are securely attached at their bottomor lower ends to the shaft 55, which shaft is properly journaled to oneof the bars 2, and for the purpose of adjusting the length of the arms54, the extensions 56 are provided,which extensions are adjustablyattached by means of the clamping bolts 57 and the slots 58. The normalpositions of the arms 54, is that indicated by the dotted lines Fig. 18,which brings the arms below the pipe.

To one of the carriage sills 5 is attached the inclined block 59, whichinclined block is adj usted upon the carriage sill, that when thecarriage has moved backward,and withdrawn the mandrel from the pipe,said inclined block will engage the roller 60, which roller is attachedto the top or upper end of the trip-bar 61, thereby depressing said tripbar and causing the bottom or lower end of said trip-bar to act upon thearm 62, which arm is attached to the shaft 55, and slightly rotate saidshaft, which in turn elevates the arms 54, thereby elevating the pipeand causing it to roll or fall to the side of the machine. After theinclined block 59 has been released from the roller 60, the arms 54 willassume their normal positions by gravity. The arms 54 are bent so as notto interfere with the IDOVO ments of the carriage. l

For the purpose of properly gathering the corrugations of the pipe, andat the same time provide a means for easily placing the pipe upon themandrel, and removing itfrom the mandrel, the corrugating flanges orridges 63 (see Fig. 7) are located somewhat closer together than thecorrugating flanges 64. It will be understood that by locating theflanges or ridges 63 and 64 as above described, that all of thecorrugations of the pipe will be equal and alike; the flanges 63 beinglocated closer together than the flanges 64, so as to compensate for thegather of the metal, and prevent a greater amount of metal from beinggathered in the seam groove corrugations, than is gathered in thecorrugations having no seams, and thereby prevent the seam corrugationsfrom expanding beyond the width of the seamless corrugations therebyleaving all the corrugations equal. 6 p

For the purpose of adjusting the guide wheels 65 and 70, the arm 66 isprovided, and is adjusted by means of the screw-threaded shaft 67, andthe wheel 68, which screwthreaded shaft is held in proper position bymeans of the yoke 69, and is held at the desired point of adjustment bymeans of the jam nut .69.

For the purpose of supporting the pipe during the time the seam isgrooved by means of the seaming wheel 7 0, the roller 71 is provided,and may take the place of the roller 29. It will be understood that byproviding the spring 32, said spring will act as a cushion, as thecarriage is brought to astop upon its return movement.

For the purpose of supporting a mandrel, when it is swung as illustratedin Fig. 23, the arm 72 is provided, which arm is provided with theroller 73, said roller being for the purpose of reducing the friction,as the pipe or skelp is placed on the mandrel. It will be understoodthat the clamp 16, should be securely bolted or otherwise attached tothe arm 13 or its equivalent, to prevent said clamp from movinglongitudinally.

Having fully described my invention, what I claim as (new, and desire tosecure by Letters Patent, is

1. In a sheet metal pipe corrugating and seam grooving machine, a frameor bed, having located thereon a reciprocating carriage provided with aswinging mandrel, substantially as and for the purpose specified.
